No mix tech.
The following weapons would become literally extinct from the Inner Sphere due to weapons that function IDENTICALLY but simply weigh less and take up less critical slots:
AC 2/UAC2 - Replaced by C-UAC2
UAC10 - Replaced by C-UAC10
UAC20 - Replaced by C-UAC20
Small Laser / ER Small Laser - Replaced by BOTH C-Er Small Laser and C-Micro Lasers
Small Pulse Laser - Replaced by C-Small Pulse Laser
Light Machine Gun / Machine Gun / Heavy Machine gun - Replaced by Clan versions
LB 2-X, 5-X, 10-X, 20-X AC - Replaced by Clan versions
Gauss Rifle - Replaced by C-Gauss Rifle
Flamer - Replaced by C-Flamer
TAG - Replaced by BOTH C-Tag and Light Tag
Laser AMS - Replaced by C-Laser AMS
ER Medium Laser - Replaced by the best weapon in the game (Clan ER Medium Laser)
LRMs - Replaced by Clan LRMs that weight 50%
Streak SRM 2/4/6 - Replaced by Clan versions
The following equipment would become extinct:
Double Heatsink - Replaced by C-Double Heatsink
BAP - Replaced by BOTH Clan Active Probe, and Light Active Probe
Endo Steel / Ferro Fibrous - Replaced by clearly superior Clan versions
Inner Sphere XL Engines / Light Fusion Engines - Replaced by the best engine type in the game
ECM - Noticing a trend here yet?
C.A.S.E. - C'mon. Literally invisible technology for all Clan mechs.
[Edit]: Targeting Computer 1 - 7 - Thought these would stay, but turns out Clan tech is just better... I know, I'm shocked to find this out too! /sarcasm
The following technology from the Inner Sphere MAY find LIMITED use:
UAC 5 - A superior version of the C-UAC 5
AC 10 - 10 damage pinpoint may find its way into a niche build.
AC 20 - 20 damage pinpoint with no charge time may find its way into niche builds.
RAC 2 / RAC 5 - Unique technology (for now) to the Inner Sphere may find its way onto clan mechs
MRM 10/20/30/40 - Unique technology (for now) to the Inner Sphere may find its way onto clan mechs
SRM 2/4/6 - Clan SRMs spread far more than Inner Sphere versions, but weigh 50%. I don't see either version disappearing in a Mix-Tech environment.
Large Laser / ER Large Laser - Would become nearly extinct (since the C-ER Medium does almost the same damage at 1/5th weight) but could find their way onto some mechs.
Medium Laser - It just MAY be used in a Mix-Tech environment... though if Clanners wanted to use this kind of weapon they REALLY should take a peek at the C-ER Small laser...
All PPCs - Every PPC fills a niche, even stacked against the Clan ER-PPC.
Heavy Gauss - Unique technology to the Inner Sphere would nearly never find its way onto Clan mechs due to Clan XL weight savings, but would not be extinct.
[Edit] Inner Sphere Targeting Computer 8 - Turns out only the Inner Sphere can get a MK 8 TC and it's just a pinch better than the Clan's MK 7.
The ONLY Technology from Clan that would actually disappear:
[Edit] I mistakenly thought Inner Sphere had an edge. I was corrected below - no edge exists.
So, in reality a "Mixed-Technology" base would be the extinction of nearly every single Inner Sphere system in the game.
